Be it known that I, ROBERTB. ROBINSON, a citizen of the United States, residing at Salt Lake Cit in the county of Salt Lake and State of tah, have invented certain new and useful vIm rovements in Track-Fasteners hich the following is a specification. My invention relates to railway track fastenings and has for its purpose to construct' such a device that will overcome the serious Objections to the present method of fastening rails to the ties.

A further Object isto provide a device of l this structure which will serve its full purpose manufacturing will be fully consistent with the installation of my improvedv track' fastening upon any railroad.

The design of the track. fastening is such that it may be readily applied or removed from the track without lthe use of speciali machinery or special tools.' 'A

With these have other o bjectsin` view which will be further'po'inted out `in'the course of the following specification and ap-'.

Referring more in'detail to the several iig- 1 ures wherein like letters Of reference designate portion ofthe tie plate adjacent the groovesy designated b F, provide the sup ort or At either side of t e base B the plate C is provided with a pair Of ribs G providing together braces for the base B that serve to Overcome'any tendency for side `movement ofA the rail.

ni's illustrated in the accom- Fig. e, is a plan view of the tie late., Fig. 5, 1s a plan view Of the sgik.

At intervals along the ribs G are apertures H for the spikes I,

resentlg which spikes are of a structure to be described. The upper surfaces o r`.t e ribs. adjacent the apertures H are countersunk, as

at K, which counters'unk surfaces'are provided with s-errations adapted to hold the screw spikes' against turninglnovement as 60 will be Obvious. The s' ikes4 I are threads by means o Which'they are more securely held within the tie. The head lof, 'the spike designated M Ihas an under slant' 65 ing surface N, which surface is adaptedto bind against the serrations of the counter' 'sunkopenings K and serves to. hold the ""and yet be of s'uch structure that the cost of spike in secured position.
